    I continue to get random white pages or “This page is not available” Error code: ERR_CONNECTION_REFUSED. https://www.careerlab.ca FRUSTRATING!

    I am not a WordPress expert buy I am computer literate and would like to fix this myself if possible.

    BTW, I can see mention of WP Super cache in the error messages below, the problem was persistent before I installed this plugin.

    Any help would be appreciated.

    error log shows:

    [05-Feb-2015 21:10:21 UTC] PHP Notice: Undefined index: HTTP_HOST in /hermes/bosoraweb170/b816/nf.careerlab/public_html/careerlab.ca/wp-content/plugins/wp-super-cache/wp-cache-base.php on line 13

    Hm, your database is refusing WordPress’s authentication method apparently.

    What version of WordPress is this, also what versions of MySQL and PHP?

    James,

    Thanks for helping me out. The WordPress version is 4.1, the latest version according to WordPress. The SQL version according to my webhost is Version: 5.5.32 and PHP is version 5.5.

    BTW when this happens if I clear the cache using the ipconfig /flushcache command I can get the site back temporarily. Just thought I would mention it.

    Hm, ok, so you have a server-level cache?

    I think in this case it would be best to gather dates and times of the incidents, then ask your hosting provider to investigate.

    Sorry James,

    I wasn’t clear, when i said that I used ipconfig /flushcache that was on my local machine not on the server.

    I have asked my hosting provider to investigate but they have reported back twice that they can find no problems and cannot replicate my experience.

    The information I posted in my first post was collected by wordpresses error log.

    I am considering wiping out the installation and starting from scratch, but I don’t want to do that unless there is no choice.

    Before you wipe absolutely everything, try downloading WordPress again and delete then replace your copies of everything except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings. Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.

    Thanks James,

    I give that a try over the next couple of days.

    Hi James,

    Interesting.

    What I did is a fresh install of WordPress in a sub-directory with a fresh sql database. Within a few minutes same problem. I am starting to think that this is a specific problem on my computer because I can’t replicate the behavior on another machine so it seems like a connection problem originating from my PC and this specific site.

    I am still investigating. I am running a full virus scan (plus malware bytes) to see what that shows. I am going to leave this thread open for the time being.

    Hope you are having a great weekend.

    If it is, please try with all browser extensions or add-ons temporarily disabled.

    Please let us know how that goes for you, and which browser (and version of) you’re using if you’re still having trouble.

    James,

    I will continue my investigations over the next couple of days. Thanks for the suggestions. My working theory at the moment is that it is a browser extension.

    I will certainly post my solution, if any ??

    I don’t normally have to post to forums, but I have to say this one is exceptionally good…and polite. Regardless of my outcome, this has been a very positive experience!

    I think I have found the solution.

    To recap, for those who are reading this with a similar problem. I was getting either a white screen or a “webpage not available” notice when I visited my own website. This could happened randomly, even from page to page. However, when I flushed the DNS cache using the windows command “ipconfig /fluashdns” the site would temporarily come back. After much experimentation and research, the problem seems to be with the windows DNS Client. By disabling it everything seems to be working fine ( at least up until now :).

    To Permanently disable DNS caching on Win Vista and Win 7
    Click the start button.
    Type services.msc in the search box.
    Click on services.msc in the search results.
    Scroll down until you see “DNS Client” in the “Name” column.
    Double click on “DNS Client.”
    Click the Stop button. (I went the extra step of selecting Disabled in the startup type drop down box.)
    To re-enable DNS caching, reverse and repeat steps 1-5.

    BTW, I have read that most modern Browsers have their own caching so disabling the Windows system is not a huge deal.

    I have had the DNS client disabled for almost 24 hours with no adverse affects and As I said above everything is working fine.
